Mars has belts of glaciers consisting of frozen water

"We have calculated that the ice in the glaciers is equivalent to over 150 billion cubic meters of ice – that much ice could cover the entire surface of Mars with 1.1 meters of ice. The ice at the mid-latitudes is therefore an important part of Mars' water reservoir," explains Nanna Bjørnholt Karlsson.

That the ice has not evaporated out into space could actually mean that the thick layer of dust is protecting the ice. The atmospheric pressure on Mars is so low that water ice simply evaporates and becomes water vapour. But the glaciers are well protected under the thick layer of dust.

but ted cruz is a bummer. it's so embarrassing when the US of A goes and flaunts all our lamest folks as candidates for presidency in front of the whole world! ugh. makes me want to crawl under a rug. every time i go traveling, i have to represent americans by saying, "i swear we're not all like that!"
